Since it's called 'emperor's domination', the emperor must be a central figure. There might also be his advisors or generals. Maybe there are some characters who oppose his rule, like rebel leaders or ambitious nobles that could also be important characters in the story.
There could be a loyal general. For example, in some stories, this general helps the emperor in battles and political maneuvers. They have a deep bond of trust and respect. The general is often highly skilled in warfare and has a strong sense of loyalty towards the emperor.
I'm not entirely sure as I haven't read it in detail. But generally, it might involve the story of an emperor, his rise to power, political intrigue, and battles perhaps.
The novels about the emperor were novels with the theme of the emperor. They usually described how a powerful emperor achieved his goals through power and conspiracy. These novels often involved political struggles, schemes, and revenge. Di Ba novels were very popular in Chinese literature. Some of the famous works included "Lord Snow Eagle","Empire","Di Ba" and so on.
One popular title could be 'The Emperor's Ascent'.
I don't know the specific main characters in the 'abyss domination novel'. However, they could be adventurers who are drawn to the abyss for various reasons like seeking power or knowledge, or they might be native creatures of the abyss with extraordinary abilities who play a significant role in the story.
Since I'm not acquainted with this light novel, we can only make some educated guesses. The emperor is surely a key character. There could be a young and ambitious person, perhaps a commoner who by some twist of fate ends up on the emperor's lap. This character would then be thrust into the complex world of the imperial court. There might also be antagonists, like jealous nobles or power - hungry ministers who oppose the main character's new - found position close to the emperor.
Maybe there is a female character who is either the emperor's love interest or a powerful sorceress who has some connection to the sword. She could be helping or hindering the emperor in his journey with the sword. And there could be an antagonist, perhaps a rival emperor or a dark lord who wants to take the sword for his own evil purposes.
Typically, the main character is the emperor himself. He could be a young and inexperienced one at the start, like in 'The Novice Emperor's Journey' where the emperor has to learn how to rule while facing various threats.
😋I recommend the following novels to you: "The Starry Sky of Insects" was similar to a sci-fi novel. The main character went from insects to alien insects and then to dark insects. The rules of the Zerg world were strong and weak. The strong survived, and the weak were eliminated. "Starting from the Zerg Swarm" was also a sci-fi interstellar civilization novel. The protagonist was bound to a game system that resembled the Zerg, and with the Zerg genes, he created the strongest Zerg. "The Insect Disaster of the Other World" was a fantasy novel about the alien world of the Zerg base and the confrontation between the Zerg army and the terrifying insect disaster. "The Reborn Bug Emperor" was another sci-fi-space love song novel. The bug dominator rose again, and the human race was afraid of the division and riots that it was about to experience. "Cosmic Zerg: Evolution and War" was also a sci-fi novel about evolution and mutation. The protagonist transmigrated to become the overlord of the Zerg race, and the creatures evolved and the war expanded. I hope you like this fairy's recommendation. Muah~If you have any other novels that you need to recommend, please feel free to tell me anytime.😗😁
The main character is the daughter of the emperor, of course. There may also be other important characters like the emperor himself, her mother if she is in the story, and perhaps some court officials or servants who play significant roles in her life.
